Combo laptop + camera bag?

[coelacanth]

Timbuk2 bag with buit-in laptop compartment + Tenba messenger bag insert.
This bag is a bit older limited edition. Doesn't say expensive camera/laptop bag.

I can carry MBP 13" (upto 15") and Leica M + 50mm, Hassy + 80mm, AND Mamiya 7 + 80mm along with films, filters, pens, etc.

I purchased a thinktank shape shifter. There are a couple of large pockets inside that will each fit an M body with a prime attached. If using a DSLR, the lenses have to be unmounted. However, I can fit a D700 + 35mm lens in 2 of the pockets - can't attach a larger lens than this though.
This bag holds plenty, compresses if needed and is comfortable to carry.

Personally I much prefer backpacks for traveling. Often I'll pack a canvas/nylon bag in my carry on or check-in luggage for the destination.
